Method CreateProposalBlock

state/execution.go:94–111

CreateProposalBlock calls state.MakeBlock with evidence from the evpool and txs from the mempool. The max bytes must be big enough to fit the commit. Up to 1/10th of the block space is allcoated for maximum sized evidence. The rest is given to txs, up to the max gas.

(
	height int64,
	state State, commit *types.Commit,
	proposerAddr []byte,
)

// Up to 1/10th of the block space is allcoated for maximum sized evidence.
// The rest is given to txs, up to the max gas.
func (blockExec *BlockExecutor) CreateProposalBlock(
	height int64,
	state State, commit *types.Commit,
	proposerAddr []byte,

	maxBytes := state.ConsensusParams.Block.MaxBytes
	maxGas := state.ConsensusParams.Block.MaxGas

	evidence, evSize := blockExec.evpool.PendingEvidence(state.ConsensusParams.Evidence.MaxBytes)

	// Fetch a limited amount of valid txs
	maxDataBytes := types.MaxDataBytes(maxBytes, evSize, state.Validators.Size())

	txs := blockExec.mempool.ReapMaxBytesMaxGas(maxDataBytes, maxGas)

// ValidateBlock validates the given block against the given state.
// If the block is invalid, it returns an error.
